Title: Method for making hydrophobic silica gels under neutral conditions
Inventor: HAHN JAMES RICHARD
IPC: C09C3/12
Filed: 1998-02-18
Abstract: The present invention is hydrophobic silica gels and a method for their preparation under neutral conditions. The method comprises two steps, where in the first step of the pH of a silic hydrosol is adjusted with a base to within a range of pH 3 to pH 7 to facilitate formation of a silica hydrogel. In the second step, the silica hydrogel is contacted with an organosilicon compound in the presence of a catalytic amount of a strong acid to effect hydrophobing of the silica hydrogel. In a preferred method, in a third step the hydrophobic silica gel is contacted with a sufficient quantity of a water-immiscible organic solvent to convert the hydrophobic silica hydrogel into a hydrophobic silica organogel.

Title: Method and apparatus for selecting joker card in poker game
Inventor: KRYZHANOVSKY ALEXANDR ALEXANDR
IPC: A63F11/00
Filed: 1999-11-08
Abstract: The present invention relates to poker game and discloses a method of selecting a joker card after each player makes an ante and is dealt five cards. A joker card is selected at random from a plurality of elements, each corresponding to one of the cards of the deck. Players view their hands and then decide whether to continue playing or to fold, basing their judgments on the available game combinations and on the random-selected joker card intended to increase the rank of a game combination. If the game is continued, the players' game combinations are compared with one another in accordance with the rank: order of winning poker hands, account being taken of the possibility of getting the highest winning hand of five cards of the same suit. The invention makes it possible to modify the traditional five-card stud poker game by introducing, without jeopardizing the poker game protection, one of the already available 52 cards as a wild card (joker) which is changed with every new hand. A random symbol, e.g. a picture of the selected card, is presented to the players on an electronic display.
Patent CA-2290740-A1 (CA)
Title: Method based on the use of bacteriophages for the detection of biological molecules in biological samples
Inventor: MONACI PAOLO
IPC: C12Q1/6804
Filed: 1998-05-22
Abstract: The present invention refers to a method that allows the use of filamentous bacteriophages to detect the presence of molecules of interest in biological samples. It consists of a series of combined operations, which are drawn up and defined according to the characteristics of the phages employed. These have, exposed on the surface of the capsid, at least one molecule, generally but not exclusively of proteic nature, capable of binding at least one molecule of interest present in said biological sample. Detection of the presence of said molecule takes place, according to the method of the invention, using the association between the molecule exposed on the surface of the phage and the genome of the phage itself. The ability to form specific complexes typical of the molecule exposed on the capsid, does enable formation of phage-molecule of interest complexes, which can be detected by means of amplification of known sequences in the phage DNA. The method according to the invention is extremely sensitive and can be used in particular for diagnostic and prognostic purposes.

Abstract: L'ensemble concerne un ensemble de frein à disque (10; 100) commandé par un système hydraulique avec un liquide de freinage. Une chambre de maître-cylindre (30) est ménagée à l'intérieur d'un cylindre concentrique (18) autour duquel un réservoir de compensation thermique interne (42) est prévu. La chambre de maître-cylindre (30) et le réservoir de compensation thermique interne (42) sont en communication par le fluide pour permettre le passage du liquide de freinage entre eux. Un piston de maître-cylindre (32) est placé en vue de son coulissement dans la chambre de maître-cylindre (30) pour générer une accumulation de pression dans le liquide de freinage et provoquer l'actionnement des freins à disques. Un piston de compensation (50) est placé à l'intérieur du réservoir de compensation thermique interne (42) et est poussé en force par un ressort (56) afin de se mettre en prise avec le liquide de freinage. En assurant une mise en prise continue entre le piston de compensation (50) et le fluide de freinage, il est possible d'éviter la formation de poches d'air dans le liquide de freinage, et de supprimer la nécessité d'un système de purge pour enlever les poches d'air.

IPC: H04B10/032
Filed: 2000-01-13
Abstract: An optical switching unit for a network node serving a service platform comprises a fault detect unit, an optical switch and a switch controller for the drop traffic. The fault detect unit detects a fault in the working or protection incoming traffic and provides a selection signal to the switch controller. The controller operates the optical switch to select the better of the two inputs basedon the selection signal. The add traffic is inserted in the respective outgoing channels using a simple passive optical splitter. Alternatively, two passive splitters may be used in the optical protection unit, in which case the input signals are switched on and off using attenuators, or simply by turning the short reach transmitters off as need be.

Title: Method for phytomining of nickel, cobalt and other metals from soil
Inventor: LI YIN-MING
IPC: C22B23/00
Filed: 1997-06-20
Abstract: Nickel/cobalt, as well as platinum and palladium metal family members are recovered from soil by growing Brassicaceae plants, specifically Alyssum in soil containing nickel/cobalt as well as other metals.  The soil is conditioned by maintaining a low pH, low calcium concentration, and the addition of ammonium fertilizer and chelating agents thereto. Nickel accumulation on the order of 2.5 percent or better in above-ground tissues is achieved, which permits recovery of the metal by harvesting the above-ground plant materials, drying, and then combusting the same, to oxidize or vaporize organic materials and recover the metals sequestered therein at 10-20 fold higher concentrations than in the soil, in a form which can be used in conventional Ni refinery or smelting operations.

Abstract: A method and apparatus for producing an array of individual business forms from a web allow two or more sets of forms from a single web to be formed and integrated in a final array, preferably an in seriatim array with a spacing between the individual forms. A web (10) at least two sheets wide is moved in a first direction (12) and slit to produce at least two web sections (16, 17). The two web sections are redirected so that they move in different paths, such as by stationary curved surfaces (23, 24) that are vertically spaced from each other and disposed at different angles to the horizontal. Typically the web sections are redirected so that they are substantially vertically aligned with each other. Then the two web sections are cut into individual sheets and the individual sheets are redirected and combined into a single array of sheets (13) with alternating sheets in the array from alternating web sections. During redirecting and combining the sheets are sped up substantially immediately after cutting so that they move at a new speed which is at least twice as great as the earlier speed.

Inventor: WONG PING CHI
IPC: H04Q3/00
Filed: 1998-09-11
Abstract: A "Local Number Portability (LNP) intelligent Signal Transfer Point (STP)" which can perform a Local Number Portability (LNP) query towards a Service Control Point (SCP) and modify the incoming Initial Address Message (IAM) with the Location Routing Number (LRN) and the Ported Dialed Number (PDN), and indicate, using the Forward Call Indicator (FCI) (M-bit), whether the number has been translated. This advantageously allows non-Advanced Intelligent Network capable Service Switching Points (SSPs) (but Integrated Services Digital Network User Part, or ISUP, capable SSPs) to support Local Number Portability (LNP) without having to upgrade the SSPs. In addition, the LNP intelligent STP system provides AIN-capable SSPs with an alternative means of LNP, which reduces both the internal switching processes and the cost for the LNP query transactions.
